Previous estimates of the potential value of higher plants in tropical forests for Pharmaceuticals are too high because analysts mistakenly used gross revenues to value drugs instead of net revenues. Correcting this error, we estimate each new drug is worth an average $94 million to a private drug company and $449 million to society as a whole. Given recent experience searching for new drugs, we estimate that the higher plants in the world’s tropical forests contain about 375 potential… 
Rainforest Pharmacopeia in Madagascar Provides High Value for Current Local and Prospective Global Uses
The value of botanical ethnomedicines in a rainforest region of Madagascar, the Makira Protected Area, is calculated using a substitution method that combines replacement costs and choice modeling and furthers arguments for the conservation of tropical forests for sustainable use.
Natural products and drug discovery
Many antibiotics are used commercially, or are potentially useful in medicine for purposes other than their antimicrobial action, and are used as antitumor agents, enzyme inhibitors including powerful hypocholesterolemic agents, immunosuppressive agents, antimigraine agents, and so on.
But What About the Forest? Mature Forests and Highland Maya Medicinal Plants
Economic arguments have been made to justify conservation of tropical mature forests. These forests are assumed to be rich in potential pharmaceuticals and medicinal plants. Conservationists and

Useful plants of the Los Tuxtlas rain forest (Veracruz, Mexico): Considerations of their market potential
The more than 160 marketable species would make it possible to develop species-diverse forests of high commercial value, as an alternative to current land use, which consists in converting forest into cattle pastures.
Ethnomedicinal aspects of angiospermic epiphytes and parasites of Kerala, India
A thorough investigation on the phytochemistry and therapeutic values of the bioactive compounds contained in these epiphytes and parasites would result in the discovery of new and valuable drugs of high potentials and of interest to the Nutraceutical and Pharmaceutical industries.
Effect of PGRs in adventitious root culture in vitro: present scenario and future prospects
The present review focuses on the application of plant growth regulators for the initiation and establishment of adventitious root cultures through various explants in vitro, and the production of root biomass could provide bioactive compounds of interest in laboratory conditions.


Assessing the Economic Value of Traditional Medicines from Tropical Rain Forests
In recent years, increasing attention has been given to the value of the tropical rain forest as a source of nontimber market products. Although estimates exist for the value of select forest
Potential consequence of plant extinction in the United States on the current and future availability of prescription drugs
This paper attempts to answer the question: What is the dollar value that can be placed on a single plant species now growing in the United States, should it become extinct? Based on available

Valuing ecotourism in a tropical rain-forest reserve.
By observing travel behavior, the study reveals that Costa Rican visitors are willing to pay considerably for the experience of visiting the site, and the present value of the site per hectare is found to be 1-2 magnitudes greater than the purchase price currently paid by the reserve for acquisition of new lands.
Managing the worlds forests.
Forests play a vital role in balancing natural systems: the stabilization of global climate and the management of water and land. 30% of the earths total land area is forested. 66% of the tropical
A New Look at the Returns and Risks to Pharmaceutical R&D
The study finds that the performance of new drugs introduced during the latter half of the 1970s was markedly better than that of early 1970s introductions, consistent with the more rapid rate of industry growth in real R&D expenditures.
